Most likely it is. As Centos 7 is going to be EOL on June 30, I'm glad to see you're testing it in a newer distro of Linux. That was going to be my first suggestion. Can you tell us if you're experiencing this problem on your Ubuntu 22 test system? If not making the cutover might be the easiest solu...

How do you have the email settings configured? Can you check the mailer logs (The location will depend on how the system is configured to send mail) and see if anything is being sent? After we know how the email settings are configured, I can dive deeper into what to look for and where for you.

You can check the logstash logs by entering journalctl -xeu logstash in a terminal window. The logstash logs can be found in /usr/local/nagioslogserver/logstash/logs . Look for anything relating to an unhandled exception. Feel free to post snippets here (sanitized, if necessary, to remove private da...

If there's a RAM issue with Elasticsearch in Nagios Log Server, there will be a RAM issue with any ELK stack. The good news on that front is that the Elasticsearch part is in the process of being replaced with Opensearch. We can't commit to a release date yet other than to say that its coming soon.

MySQL and MariaDB freqently have package conflicts, so I wouldn't recommend that.

Which packages are installed? mysql or maria? execute sudo yum list installed to check.

Check to see if either service is installed:

systemctl | grep -i mysql
systemctl | grep -i maria

To be honest, I think this one might require using a support call. https://answerhub.nagios.com/support/s/

Good to know! To be honest, I'm not certain that Elasticsearch is meant to be used in the manner you're using it (with two nodes of the cluster divided across data centers. Personally I like the idea for availability, but I'm just not sure its officially supported for that. Its great that adjusting ...

We're working to make the migration as painless as we can, but it won't be completely pain free because of the huge jump from Elasticsearch 1.7.6 in the current NLS product. Those details are being worked on at the moment.

The root password should be the mysqlpass value in the xi-sys.cfg file. MariaDB is a fork of MySQL and the two are often used interchangeably. For this purpose they're equivalent. Try using that value to log in to the database both from the mysql client on the XI system and the Database. IF not, you...
